- •
Angular insensitivity vegetation index (AIVI) for estimating wheat N was developed.
- •
The index was compared with traditional indices across conditions and view angles.
- •
Optimal viewing zenith angles were determined and characterized.
- •
The AIVI improves LNC predictions, monitoring stability and view angle independency.
